I did enable it for Tegra at one point with no ill effects except for
breaking warmboot, which relied on function ordering. I notice the
no-toplevel-reorder flag on x86 but not with ARM. But I assumed there
must be some reason it is not used and thought this patch safer, since
it is just a minor tweak on a series that has has some review.

IXP does enable it, but not ARM in general. Most archs use
function-sections although not all. Perhaps there are some boards
which don't work with this flag?

Albert do you know?
